.nfs* lock files

I have innumerable files in the "locks" directory with the prefix ".nfs". There are several of these every minute of every day. I think it may be related to a problem I have regarding the cgi script "listinfo". When I try to invoke "<mailman-server>/mailman/listinfo" I get ----------------------------------------------begin here------------------------------------------------------------------- Bug in Mailman version 1.1 We're sorry, we hit a bug!

Re: [Mailman-Developers] cookies

[Ricardo Kustner] > you used 2 test cookies in your example, but i'm not sure if that's > necessary... It is once others beside me get a user database :), because then they will have cross-list authentication using a single cookie. In that scenario it would be a shame if the test cookie overwrote a valid authentication cookie for some other list. > also, AFIAK, deleting a cookie can be done by re-setting it with an > empty value (though i believe there are some old versions of either > IE or Netscape which have a bug with this feature) I'd prefer to go with the method described in RFC 2109: 4.2.2 Set-Cookie Syntax [...] Max-Age=delta-seconds Optional. The Max-Age attribute defines the lifetime of the cookie, in seconds. The delta-seconds value is a decimal non- negative integer. After delta-seconds seconds elapse, the client should discard the cookie. A value of zero means the cookie should be discarded immediately. > > Of course, if there are any (major) browsers in use out there that > > doesn't understand Max-Age, it would be a bad idea to change Mailman. > this is the first time I've heard about Max-Age RFC 2109 is dated February 1997, and one of it's authors was a Netscape employee. I'll try issuing Cookies with Max-Age instead of Expires for our own users, and let you know how it goes >-) -- Harald

Current round of checkins are finished
by bwarsaw＠python.org May 10, 2000

May 10, 2000

I've checked in all my current modifications to make losing messages much less likely. I'm sure there are bugs lurking about, so be careful if you're running the CVS snapshot. I'm going to spend a few hours over the next couple of days testing things so watch for more patches. If you do play with the snapshot and find problems, please let me know. Figure if I get some time, there will be a beta this weekend. -Barry

Re: Extraordinary locking mechanisms...

What is that something? Chris pointed at that mailman runs as a distributed system, so IPC won't work. The idea, though, of using something other than the filesystem for locking makes good sense. The locking could be based on a server that communication with other mailman components over a socket. It would look basically like the Javaspaces leasing service. (Leases are basically locks that timeout.) The only worry I would have is about crashes of the lease service. For a single machine, it could run under init; for multiple machines, a leader election protocol would be necessary to guard against machine crashes. Jeremy

What is Basic-Authorization? If it doesn't involve a HTTP POST of the admin login page, I believe it will not work (out of the box, anyway). -- Harald
